Please help my babies what’s going on

Hi so I’m trying to figure out what’s wrong with my babies I’m in bio bizz almix soil I’ve been watering with 1ml cal mag 1ml booster per litre for a while i recently upped it to 2ml of each it hasn’t changed much hasn’t got any better I’m watering with ph 6.5
Using Mars hydro ts3000 led light isn’t too close any help would be much appreciated

What age are they cause bio bizz all mix has enough in it to feed for a months. Mine are 5 weeks old ans I’ve only fed them nutes 2 time just water ans molasses the rest of the Time. First kid was a week ago second pic was today

It looks like calcium deficiency to me which, if you're already using cal mag, probably means it's getting a bit acidic at the bottom of your medium. Try using a heap of your 6.5ph input (slowly) and measure what runs out. If it's coming out at less than 6 (I'll bet it's around 5.5 or 5.6 if you go real slow), then keep flushing through until it's much closer to the 6.5 that's going in.
You may struggle to get it over 6.1, but have another go on the next day - it should improve.
Good luck.

You're feeding just calmag and a booster? What about nitrogen and micronutrients? Plants still use nitrogen in flower. You don't want to eliminate it completely or your leaves will go yellow. Too much calmag can lockout P/K and other things as well. Why are you using calmag every watering? You're in soil. Are you using RO water? That soil combined with tap water should have all the Ca needed.

Calmag is overused. It's not a requirement in many growing conditions and excess use can actually lead to nutrient issues. I'd drop the calmag and booster and just feed a balanced bloom nutrient that contains N and micronutrients.
